Does anyone know how to spell または write this name, in romanized Japanese?

Well, I'm not good with Japanese words at all and I speak Japanese very poorly... but I like to use Japanese names and words for my stories too! I've noticed over the years that for some Japanese names that mean "first son of..." they tend to have the word meaning whatever and then ichi at the end of it that means first. Like, for example, Seiichi, which means "first son of Sei" and Ryoichi, which means "first son of Ryo"... So maybe あなた can have the characters name be "Tsukiichi" for "first son of the moon"?

I've also noticed they like to put "ko" at the end of names for "child of the...", like Tadako for "child of Tada" and Yoshiko for "child of Yoshiko", so perhaps あなた could also have "Tsukiko" for "Child of the moon"?

That's all I have cause that is about the extent of my Japanese knowledge, lol! And good look with Ghost of the Earth, cause you've stumped me on that one!
